当我尝试使用代码生成器添加脚手架项目时，我收到以下错误消息：

运行生成器时的异常输出：

目前我尝试了好几个小时，但我没有发现失败:(

这是我的 project.json 文件

【解决方案1】：

您有一个依赖项 Microsoft.Extensions.CodeGenerators.Mvc 和更高版本的 Microsoft.VisualStudio.Web.CodeGenerators.Mvc。我认为这与 Microsoft.Extensions 是错误的。

【解决方案2】：

我的意思是，您的框架定义不正确。

在您的项目中：

"frameworks": {
    "netcoreapp1.1": {
      "imports": [
        "dotnet5.6",
        "dnxcore50",
        "portable-net45+win8"

检查一下：

"frameworks": {
    "netcoreapp1.1": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.1.0"
        }
      },
      "imports": "dnxcore50"
    }
}

那么，您现在可以将 Microsoft.Extensions.CodeGenerators.Mvc 用于 dnx。
